Reverse Osmosis (The cost saving process).
To understand Reverse Osmosis we must first understand osmosis. During natural osmosis, water flows from a less concentrated solution through a semi-permeable membrane to a more concentrated saline solution until concentrations on both sides of the membrane are equal. (see figure)

                                                               OSMOSIS                     REVERSE
1) Reverse Osmosis (Cleaner water on left side) 
Reverse Osmosis requires external pressure to reverse the natural osmotic flow. As pressure is applied to the saline solution, pure water flows from a more concentrated saline solution through the semi-permeable membrane.  
2) Reverse Osmosis Membrane 
A Reverse Osmosis membrane has a thin microporous surface which rejects impurities, but allows uncontaminated water to pass through.
The membrane rejects bacteria, pyrogens and 85%-95% of inorganic solids. Polyvalent ions are rejected easier than monovalent ions. Organic solids with a molecular weight greater than 300 are rejected by the membrane, but dissolved gases pass through.
Reverse Osmosis is a percentage rejection technology. The purity of the product water depends on the purity of the inlet water. The purity of the Reverse Osmosis product water is much higher than the purity of the feed water. 
Reverse Osmosis is regarded as the most cost effective way to purify water. Depending on the purity of the feed water the wastage may vary from 3 to 1 up to 5 to 1 in order to have an end product of purified water. 
The above seems high but just take note of the average water price in South Africa: 
                                                0 TO 6 000 LITERS @ R 3.50  PER 1000 LITERS
                                     7 000 TO 12 000 LITERS  @ R 5.00  PER 1000 LITERS
                                     13 000 TO18 000 LITERS @ R 6.56  PER 1000 LITERS
                                    19 000 TO 24 000 LITERS @ R 7.58  PER 1000 LITERS
                                    25 000 TO 30 000 LITERS @ R 8.66  PER 1000 LITERS
                                    31 000 TO 42 000 LITERS @ R 9.37  PER 1000 LITERS
                                    43 000 TO 72 000 LITERS @ R 10.03 PER 1000 LITERS
                         72 000  LITERS AND UPWARDS @ R 10.73 PER 1000 LITERS 
The average household consumes about 200 to 300 liters of drinking water per month. In ordinary language, more or less R 10.00 to R 12.00 of water is "wasted" during the Reverse Osmosis process in order to produce 200 to 300 liters of PURE drinking water. This is cheap!
How much does a single 340ml bottle of bottled water cost? ± R5.00? Against the 300 liters of PURE, GOOD TASTING, HEALTHY WATER at R 10.00 to R 12.00 of "wasted" water there is just no comparison.  
The above facts discredit any argument about water wastage. To try and avoid the "wasted" water by filtering is many times costlier because of the need to regularly replace the filters as they will get polluted almost monthly - with no guarantee of PURE water through the Reverse Osmosis process, a process which not only saves a lot of money by not having to replace filters constantly, but also ensures that you are NOT drinking polluted water. Many arguments about "wasted" water have been resolved amicably through the abovementioned facts about the Reverse Osmosis process.
